我有一个带有适配器的RecycleView,它显示了一个服务器列表,用户必须选择一个服务器.

当我在onClick()方法中调用notifyItemChanged(previousPosition)以使旧服务器未被选中并选择新服务器时,这使得RecycleView列表完全跳到列表中间.

当我点击RecycleView列表中最后2或3个服务器之一时,会发生此问题

这是我的RecyclerView.Adapter的代码:

public class ServerAdapter extends RecyclerView.Adapter<ServerAdapter.ServerViewHolder> {

    private List<Server> listServers = new ArrayList<>();
    private int[] icons = new int[]{R.drawable.server1,R.drawable.server2,R.drawable.server3,R.drawable.server4,R.drawable.server5,R.drawable.server6,R.drawable.offline};
    private int selected = 0;
    private int previousSelected = 0;

    public ServerAdapter(List<Server> listServers){
        this.listServers = listServers;
    }

    @Override
    public ServerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.server_relative_layout,parent,false);
        return new ServerViewHolder(view);
    }

    @Override
    public void onBindViewHolder(final ServerViewHolder holder, final int position) {
        if(position == selected){
            holder.getBackground().setSelected(true);
        }else{
            holder.getBackground().setSelected(false);
        }
        holder.getBackground().setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) …
